Use the formula or complete the square.
The zeroes of the quadratic can be real and rational; real and irrational; complex conjugates.
If the quadratic is ax²+bx+c, x=(-b+√b²-4ac)/2a.
If b² > 4ac the solutions are real. If b²-4ac is a perfect square, the solutions are real and rational; otherwise they’re real but irrational.
If b² < 4ac the solutions are complex.
Answer:
y - 4 = 3(x- (-1) ---> y-4 = 3(x+1)
Step-by-step explanation:
y - 4 = 3(x + 1)
y - 4 = 3x + 3
y = 3x + 7
then plug in (-1,4)
4 = 3(-1) + 7
4 = -3 + 7
4 = 4
Point slope form looks like:
y - y₁ = m(x - x₁)
For this case, what we must do is multiply the depth of the fish by the fraction of depth of the turtle.
We have then:
(-3/4) * (1/3) = (- 3 * 1) / (4 * 3) = - 1/4 mile
Therefore, the depth of the turtle on the surface of the water is:
-1/4 mile
Answer:
the turtle's depth is:
-1/4 mile
Answer:
The distance between the points is five for the first one and 7 for the second one.
